The 8-shot panorama below features telephone lines that are not stitching correctly in Photoshop CS6 or PTGui 9 with the standard software settings. The images were shot with an 18mm Olympus lens mounted vertically on a 5D Mark II. The camera was on a nodal slide, but the lines moved during the long exposures. Here is a folder with a zip file that has 2000x3000 jpeg versions of all 8 images (33MB): http://dl.dropbox.com/u/106817539/pano_challenge.zip

Do you have a good panorama stitching technique for correcting parallax error in long sections of telephone wires? The warp tool and masking in Photoshop is too tedious. There has to be a better way. Thanks for taking the time to give this stitch a try -- I'll be curious to see if anyone has a good way to fix the wires!

Looks like a prime candidate for either something like the healing brush or content aware (scale is what I'm thinking, but not right) - that will take out the poles and the wire pretty easily... I think.

Looks to me like you have four warps to do and you're all set. It doesn't really take that long in my experience, and I really can't see any other way around it. I might have a shot at this later when I've got some time.
Sorry if I'm not very helpful... Interesting shot, btw.

@wbrad - I've tried warping and cloning. In order to get the angles to be convincing, it would take a long time. But maybe someone has a better, faster, stronger warping or cloning technique to solve this issue?

@Jeffrey - I'm guessing you're asking why keep the power lines? Simple -- I like the arc of the lines through the sky, and I don't have any problem with infrastructure being in my photos. That being said, I want to keep this thread focused on solving the problem, and not turn this into a discussion of aesthetics.

I've made a quick little diagram to show how I usually handle an issue like this. The outlines show the three areas I would select, then I would actually use 'distort', not 'warp', in the directions shown. Then I use the history brush to clean up around each selection, and a little bit of cloning to patch up any imperfections in the joins.
I can usually manage seamless repairs in a few minutes.

If all you want to do is correct the discontinuities in the power lines, I suggest giving Puppet Warp a shot.

1. Do a copy merge of a section of the power line up to the break. You want to select a long enough piece of the line that the slight change in direction won't be noticed.
2. Paste to a new layer.
3. Do an Edit>Puppet Warp on the layer with the piece of power line. Select a pivot point at each end of the segment as close to the line as possible.
4. Move the end of the line to eliminate the discontinuity.
5. Accept the Puppet Warp change.
6. Use a quick clone edit to remove any fuzziness around where the line connects.

Here is a snapshot of the Puppet Warp edit just prior to moving the endpoint:

I've had pretty good luck with PS by stitching shots in groups. This pano gave problems connecting the single strand of barbed wire -- shot on a standard tripod. If I recall, I started with the middle 3 shots and then kept adding to each end. I still ended up with some minor misalignment that could be handled with Eyeball's puppet warp.

Make the pano as a layered file. Then, starting with the topmost layer and working down through the pile, try adding selective masking. usually you can find a spot where everything aligns. Sometimes a nudge on the layer with liquify is also useful.

Distorting the layers often creates problems elsewhere in the overlap.
